I have also found that if you turn off automatic updates in the security centre you don't get the SVCHOST problem, I experience the same problem (of svchost takes 99% of CPU usage) whenever i manually check for updates with microsoft website. Can anyone tell me the solution for this?

Well! I turned off automatic updates and I still experience the problem. My anti-virus/anti-spyware are McAfee and up to date.

There is a solution that worked for me at this site:

Be aware, however, that this procedure disabled my USB wireless network adapter. I had to unplug my adapter, then plug it back in, and when my network reconnected I had to reenter my security key.

I have svchost spiking to 100% every few hours and locking up my computer. I then go to the Task Manager, identify the process that's sucking 90-99% and end it. As soon as the process is ended everything goes back to normal. But it's so annoying I'm considering reinstalling the OS.

this happens on boot up sometimes i let it do what it needs 2 for maybe 2-3mins then its ok, when it first occured use to end svchost.exe in options this stopped it but the desktop would flicker then change to classic view and icons would disappear almost like a semi safe mode look, then for some reason i couldnt end process, knowing the importance of this file i no longer end process

I'm running XP and it is updated. When I turn on my computer I have over 5 gigs free on my C drive(my drive is partitioned) after a few minutes I get an error message that I have no space left on C. When I checlk I have only 700k free. When I reboot the same thing happens again.

My cpu usage runs at 90%-100% without me running any unusual progs. Suddenly it drops to 15% or so, without reason. I doubt some1 is hijacking mp pc from under my nose. SpyDoctor and Spyeraser didn't find this hijacker. But i got 8 svchost.exe processes running under System, Local services and Network service. Is that normal? could any of these be a hijacker?

If you're having an svchost error go to this page:

It helped me out tons.

I found a stupid patch to fix the problem.
- First thing I do when I start windows is opening my task manager and sort by "Image Name". I slide down to the list of "svchost processes". I then run my browser as usual. For sure, soon I get that 100% CPU usage. Task manager is still accessible without any delay. I select the "svchost.exe" at 100% and "END THE PROCESS". It takes few seconds. Once cancel, that "svchost.exe" leave my computer as long as I stay connected. It's cumbersome, but it works for me.
NOTE: If I switch user in Window, the same exercise as to be redone.

- It worth a try.
